This project contains a collection of classification models in Python that predict if a patient has Atrial Fibrillation (AFib) based on the given Electrocardiography (ECG) signals of the patient.

The models are written in Python using scikit-learn and TensorFlow Keras. wfdb and Neurokit2 are used to analyze ECG signals and measure data to export them to a dataset (in the data folder as .csv files).

The ECG signals are taken from the open-source MIT-BIH Atrial Fibrillation Database (in data/afdb/ and the PTB-XL ECG Database (in data/ptb/).

The afdb and ptb folders contain the respective database signals, but the actual files are not pushed as they are too large. You can download them on the official website (the link is in the citation below).

The models folder contains the generated files for the models, also not pushed to GitHub.

The reports folder contains the auto-generated report for each model, including the accuracy and confusion matrix.

Used RandomForestClassifier from sci-kit learn to classify an ECG signal on a 10-second interval as Normal or AFIB.

Used TensorFlow to create a 3-layer LSTM (RNN) model to classify ECG signals on 10-second intervals as Normal or AFIB.

Used TensorFlow to create a 3-layer CNN model to classify ECG signals on 10-second intervals as Normal or AFIB.

Used SVC from sci-kit learn to classify ECG signals on 10-second time intervals as Normal or AFIB.

Used xgboost to create a Gradient Boosting model to classify ECG signals on 10-second intervals as Normal or AFIB.

Used TensorFlow to create a Resnet model with 1 Convolutional layer and 2 Residual blocks to classify ECG signals on 10-second intervals as Normal or AFIB.
